(Mark goes to get on the elevator, the doors open and Erica and Callie are standing there)
Mark (smirks): Ladies.
Callie: He's thinking about a threesome.
Mark: I am not.
Callie: You are. You have been... all day.
Mark: Okay, fine. I got a new leaf, not a lobotomy.
Erica: You couldn't handle the two of us.
Mark: Oh, but I could. I won't, but I could.
Erica: You wouldn't find it intimidating?
Mark: Not at all. (Callie laughs. Erica grabs her face and kisses her)
Erica: See? Too much for 'ya. (exits the elevator, leaving Callie standing there shocked and dismayed)
Mark: Damn it! On-call room, right now. (he exits the elevator, Callie is still in shock, it takes her a minute to follow him)
